“I first auditioned for John and I wished that I was auditioning for Stephen because I had read the script and I just related much more to that character,” Robbie told Access Hollywood. “I like [the] origin story of this kid, very normal kid, used to have a good life and a great family and friends and then everything was pretty much stripped from him and he doesn’t know why or what’s going on, so it seemed like a really fun character to start from scratch and go on this incredible journey and finding out he has superpowers and living in this incredible world while still staying grounded and being a normal kid and finding my way through it.”
